Grade Level: 10-12

Objective: By the end of this lesson, students will learn the process of restoring a rusty machete, understanding the importance of maintenance and preservation. They will develop skills in problem-solving, critical thinking, and practical application of tools and techniques.

Common Core Standards:
- CCSS.ELA-LITERACY.W.11-12.2: Write informative/explanatory texts to examine and convey complex ideas, concepts, and information clearly.
- CCSS.ELA-LITERACY.RST.9-10.3: Follow precisely a complex multistep procedure when carrying out experiments, taking measurements, or performing technical tasks.
- CCSS.MATH.CONTENT.HSN.Q.A.1: Use units as a way to understand problems and to guide the solution of multi-step problems.

Materials:
- Rusty machete (can be sourced from a local hardware store or provided by the teacher)
- Safety goggles
- Protective gloves
- Sandpaper (various grits)
- Steel wool
- Vinegar
- Baking soda
- Lubricating oil
- Cleaning cloth
- Writing materials for note-taking and reflection

Procedure:

1. Introduction (10 minutes):
- Engage students in a discussion about the importance of tool maintenance and preservation.
- Explain the process of restoring a rusty machete.

2. Safety Measures (5 minutes):
- Instruct students to put on safety goggles and protective gloves before handling the machete.
- Emphasize the importance of safety precautions when working with tools.

3. Assessment and Planning (10 minutes):
- Have students assess the condition of their rusty machete, noting the extent of rust and damage.
- Instruct them to develop a restoration plan based on the condition of the blade.

4. Removing Rust (20 minutes):
- Demonstrate the step-by-step process of removing rust from a machete blade:
a) Use sandpaper or steel wool to scrub away loose rust.
b) Create a rust removal solution by mixing vinegar and baking soda.
c) Soak the machete blade in the solution for a specific period, depending on the severity of rust.
d) Scrub the blade using sandpaper or steel wool again to remove remaining rust.

5. Polishing and Smoothing (15 minutes):
- Instruct students to use progressively finer grits of sandpaper to polish and smooth the blade.
- Demonstrate proper techniques for maintaining an even surface and removing scratches.

6. Lubrication and Preservation (10 minutes):
- Explain the importance of lubricating the machete blade to prevent future rust.
- Instruct students to apply a thin layer of lubricating oil to the blade and handle.

7. Cleaning and Final Evaluation (10 minutes):
- Instruct students to wipe down the machete blade with a cleaning cloth to remove any residue.
- Have them evaluate their restored machete and reflect on the effectiveness of the restoration process.

8. Reflection and Discussion (10 minutes):
- Lead a class discussion on the challenges and successes students encountered during the restoration process.
- Encourage students to reflect on the importance of tool maintenance and preservation.
